tion with the robins at least, for never have I seen and heard of 

 so many nests of robins built on houses, under verandas, over 

 doorsills, etc., and that in places where trees are plentiful. 



Finally the untowardliness of the season caused some species 

 to remain with us a much shorter time than usual. They delayed 

 coming to us longer than under normal conditions, and, wanting 

 to get to their breeding ranges at the usual time, they had to cut 

 short their sojourn here. This was the case with the rusty 

 grackle and the white-crowned sparrow; the tree sparrow too 

 was not seen by most observers, and the blackpoll warblers, 

 while a few single individuals were seen much later than usual I 

 observed one at High Falls, Que., as late as June 12th made 

 the total length of their stay shorter than otherwise, owing to 

 their much later arrival. Bay-breasted, Tennessee and blackpoll 

 warblers, olive-backed thrushes and pine siskins were seen and 

 heard in full song as late as June 7th at Major's Hill Park, which 

 will probably not happen again for years. 



I add a comparative list, which begins where the one in the 

 Mav number left off, with April 22nd.
